As a teenager I found it hard to picture the 3D structure of DNA, proteins and other molecules. Remember we didn’t have a computer then, no videos, nor 3D-pictures or 3D models.

I tried to fill the gap, by making DNA-molecules of (used) matches and colored clay, based on descriptions in dry (and dull 2D) textbooks, but you can imagine that these creative 3D clay figures beard little resemblance to the real molecular structures.

But luckily things have changed over the last 40 years. Not only do we have computers and videos, there are also ready-made molecular models, specially designed for education.
